The linkage between the sea ice concentration (SIC) over the Barents-Kara Seas in November–December (SIC_BKS_ND) and the stratospheric polar vortex (SPV) in subsequent January (SPV_Jan) is investigated. It is found that SIC_BKS_ND is positively (negatively) correlated with SPV_Jan for the period 1979–1995 (1996–2009). Further analyses reveal that, during 1979–1995 (1996–2009), SIC_BKS_ND is relatively higher (lower), accompanied by smaller (larger) interannual variability with its center shifting northwest (southeast). Meanwhile, the polar front jet waveguide is relatively stronger (weaker). The simultaneous anomalous eastward-propagating Rossby waves excited by anomalously low SIC_BKS_ND are stronger (weaker), which results in the stronger (weaker) negative-positive-negative wave-train structure of geopotential height anomalies over Eurasia, with the location of these anomalous height centers shifting remarkably westward (eastward). Such changes tend to enhance (suppress) vertically propagating tropospheric planetary waves into the lower stratosphere at high-latitude via constructive (destructive) interference of anomalous tropospheric wave-train structure with the climatological planetary waves, subsequently weakening (strengthening) SPV_Jan. However, in conjunction with anomalously high SIC_BKS_ND, the interference of the tropospheric wave-train structure anomalies and their climatologies shows an opposite distribution to that of low SIC_BKS_ND anomalies, which leads to a strong (weak) SPV_Jan anomaly during 1979–1995 (1996–2009).

研究了 11 月至 12 月巴伦支海的海冰浓度 (SIC) (SIC_BKS_ND) 与随后 1 月 (SPV_Jan) 的平流层极涡 (SPV) 之间的联系。发现 SIC_BKS_ND 在 1979-1995 年（1996-2009）期间与 SPV_Jan 呈正（负）相关。进一步分析表明，1979-1995（1996-2009）期间，SIC_BKS_ND相对较高（较低），伴随着较小（较大）的年际变率，其中心向西北（东南）移动。同时，极前射流波导相对较强（较弱）。由异常低的SIC_BKS_ND激发的同时向东传播的异常Rossby波更强（更弱），这导致欧亚大陆位势高度异常的负-正-负波列结构更强（更弱），随着这些异常高度中心的位置显着向西（向东）移动。这种变化倾向于通过异常对流层波列结构与气候行星波的建设性（破坏性）干涉来增强（抑制）垂直传播到高纬度低平流层的对流层行星波，随后削弱（加强）SPV_Jan。然而，与异常高的 SIC_BKS_ND 一起，对流层波列结构异常及其气候学的干扰显示出与低 SIC_BKS_ND 异常相反的分布，这导致了 1979-1995 (1996-) 期间的强（弱）SPV_Jan 异常2009）。这种变化倾向于通过异常对流层波列结构与气候行星波的建设性（破坏性）干涉来增强（抑制）垂直传播到高纬度低平流层的对流层行星波，随后削弱（加强）SPV_Jan。然而，与异常高的 SIC_BKS_ND 一起，对流层波列结构异常及其气候学的干扰显示出与低 SIC_BKS_ND 异常相反的分布，这导致了 1979-1995 (1996-) 期间的强（弱）SPV_Jan 异常2009）。这种变化倾向于通过异常对流层波列结构与气候行星波的建设性（破坏性）干涉来增强（抑制）垂直传播到高纬度低平流层的对流层行星波，随后削弱（加强）SPV_Jan。然而，与异常高的 SIC_BKS_ND 一起，对流层波列结构异常及其气候学的干扰显示出与低 SIC_BKS_ND 异常相反的分布，这导致了 1979-1995 (1996-) 期间的强（弱）SPV_Jan 异常2009）。随后削弱（加强）SPV_Jan。然而，与异常高的 SIC_BKS_ND 一起，对流层波列结构异常及其气候学的干扰显示出与低 SIC_BKS_ND 异常相反的分布，这导致了 1979-1995 (1996-) 期间的强（弱）SPV_Jan 异常2009）。随后削弱（加强）SPV_Jan。然而，与异常高的 SIC_BKS_ND 一起，对流层波列结构异常及其气候学的干扰显示出与低 SIC_BKS_ND 异常相反的分布，这导致了 1979-1995 (1996-) 期间的强（弱）SPV_Jan 异常2009）。
